Abstract
Abstract A receptacle for storing long articles, including a rectangular container having article-receiving openings at one end. Hingedlyconnected closure flap means are provided for normally closing the container openings, said closure flap means comprising a pair of normally closed opposed vertically arranged closure flaps. The hinge means that connect the lower ends of the closure flaps are connected for vertical sliding movement relative to the end walls of the container, whereby when the closure flaps are hingedly opened, they may be displaced vertically downwardly to a position in which the closure flaps are locked open and enclose the container.
